Detailed Solution

Concept: An ammeter is a tool used to gauge the current flowing through a particular circuit. We've seen this in laboratories, and we are aware that in order to measure current in a circuit, the ammeter must always be connected in series. We are also aware of AC and DC. Now let's observe.Charge flow rate is expressed as electric current. Alternating Current is the term for a current that results when the direction of an electric charge changes often (AC). The term "AC ammeter" refers to the instrument used to measure the alternating current in an electric circuit. We must now determine if we may use AC ammeters both in AC and DC circuits or just in AC circuits. Only now do we need to check for DC circuits since, as the name says, it is employed in AC circuits.
An ammeter is a tool used to gauge the current flowing through a particular circuit.
It is used to measure the current in a circuit, the ammeter must always be connected in series.
Hence, the correct option is 3 .
